Title: Method and system for the detection of removed objects in video images
Inventor: AU KWONGWING
IPC: G06K9/00
Filed: 2007-06-05
Abstract: A method, system and program product for the detection of removed objects in video images is disclosed. An object (or objects) is within a fixed camera's FOV (Field of View), is designated to be monitored. If an object is not designated, an algorithm can be used to segment and identify all the objects in the image that is acquired by a fixed camera. In such case, all these objects can be monitored. A reference frame around the monitored object that also includes the surrounding background can be determined. The object can be extracted out of the reference frame, thereby creating a "reference with hole" image and an object reference image. The hole in the "reference with hole" image can be filled by either an in-painting algorithm or a texture synthesis algorithm depending on the complexity of the surrounding background.

Abstract: 1,261,636. Chromium plating elongated articles. INSTITUTUL DE CERCETARI TEHNOLOGICE PENTRU CONSTRUCTII DE MASINI. Feb. 26, 1969, No.10157/69. Heading C7B. An elongated metallic surface is chromium plated section by section, each section being plated by arranging it in a plating electrolyte in spaced relation to an anode and disposing a pair of screens at cathode potential at the limits of the section and at equal distances from the anode. Fig.1 shows an elongated rod 1 to be plated the section being plated being sealed in plating tank 2 by sealing members 3. A perforated anode 4 of Pb-Sb or Pb-Sn-Ag alloy surrounds the section, and two screens, one of which 5a, is shown, surround the rod at the ends of the section. Each screen, Fig.2, is made of two semi-annular elements of insulating material which together make an annular member 6 with a thinwalled annular metallic element 8 mounted thereon by screws 7. The tank 4 is filled with chromium plating electrolyte and the article is given anodic treatment for 90 seconds at increasing current density of 12-40 amps/sq. dm. The polarity is reversed and plating is operated at 40-60 amps/sq. dm., the electrolyte containing 200-250 g/l of CrO 3  and 2-2À5 g/l of sulphate ions. The screens ensure a chromium layer of progressively diminishing thickness in the region of the screens, and this is built up to a layer of uniform thickness by operations on successive sections.
